My yearly bicycle tour this year was from Munich to Praha via Köngissee.
On the first part I followed the Bodensee-Königssee-Radweg, then following the rivers from Königssee till Salzach, I joined EuroVelo 7. This way led me via Salzach, Inn, Donau to the Czech Republic. There I loosely followed the river Moldau (Vlatva) till Praha.
You can see my tracks on the interactive map I created:
For the map I used the following tools:
Viking - Viking GPS data editor and analyzer
For trimming the gpx tracks.
As the basis for the map.
Leaflet-ui - Leaflet presets for common user interface customizations
For simple UI controls.
leaflet-elevation.js - A Leaflet plugin that allows to add elevation profiles using d3js
For displaying the elevation profile of my gpx tracks.
leaflet-gpx - GPX plugin for Leaflet
For loading the gpx tracks.
